A Comprehensive Analysis of Hyperbolical Fluids in Modified Gravity
Entropy, 2022 This paper is devoted to understanding a few characteristics of static irrotational matter content that assumes hyperbolical symmetry. For this purpose, we use metric f(R) gravity to carry out our analysis.

Adam Smith et la physique de Newton
Œconomia, 2012 In most of Smith's writings we find references to the natural philosophy of Newton. Beyond the use of Newtonian concepts and laws to deal with specific issues, we would like to focus on the relationship between the Smithian representation of the social ...

Gravitation in Unified Scalar Field Theory
Universe, 2021 The scalar field of space-time film is considered as unified fundamental field. The field model under consideration is the space-time generalization of the model for a two-dimensional thin film.

Universe, 2019 We report on the behavior of two-level quantum systems, or qubits, in the background of rotating and non-rotating metrics and provide a method to derive the related spin currents and motions. The calculations are performed in the external field approximation.

Dark Energy as a Born-Infeld Gauge Interaction Violating the Equivalence Principle [PDF]
, 2006 We investigate the possibility that dark energy does not couple to gravitation in the same way than ordinary matter, yielding a violation of the weak and strong equivalence principles on cosmological scales.

Constraints on Lorentz Invariance Violation with Multiwavelength Polarized Astrophysical Sources
Galaxies, 2021 Possible violations of Lorentz invariance (LIV) can produce vacuum birefringence, which results in a frequency-dependent rotation of the polarization plane of linearly polarized light from distant sources.

Matrix theory of gravitation [PDF]
, 2011 A new classical theory of gravitation within the framework of general relativity is presented. It is based on a matrix formulation of four-dimensional Riemann-spaces and uses no artificial fields or adjustable parameters.

Gravitational and Anti-Gravitational Applications
International Journal of Geosciences, 2017 It is now possible to partially deflect gravitation away from an object so that the gravitational attraction on the object is reduced. That effect makes it possible to extract energy from the gravitational field, which makes the generation of gravito-electric power technologically feasible.

Potential of a Spheroid with Generalized Exponential Density Distribution
Open Astronomy, 2015 The internal potential of an inhomogeneous layered spheroid with a small ellipticity and general exponential density distribution is derived in an analytical form.
